AS3 ViewStack内容剪辑

Question

我有下一段代码(Flash Builder 4.5)

这是一个主要的应用程序文件，用于测试视图堆栈组件。

TabPanelTest

    </fx:Declarations>
    <fx:Script> 
        <![CDATA[
            import mx.events.FlexEvent;

            protected function creationCompleteHandler(event:FlexEvent):void
            {
                tp.AddPanel("111", new Button());
                tp.AddPanel("444", new TestPanel());
                tp.AddPanel("2222222", new Button());
                tp.AddPanel("3333333333", new Button());

            }

            protected function button1_clickHandler(event:MouseEvent):void
            {
                // TODO Auto-generated method stub
                tp.RemoveAllPanels();
            }

        ]]>
    </fx:Script>

    <ns1:TabPanel id="tp" x="25" y="27" width="321" height="199">
    </ns1:TabPanel>
    <s:Button x="439" y="25" label="Кнопка1" click="button1_clickHandler(event)"/>

</s:Application>

这是TabPanel，它有公共方法AddPanel和RemoveAllPanels。

TabPanel

            protected function creationCompleteHandler(event:FlexEvent):void
            {
                //buttons1.dataProvider=new ArrayCollection();
            }

            public function AddPanel(name:String, element:IVisualElement):void{
                var panel:NavigatorContent=new NavigatorContent();
                panel.label=name;
                panel.addElement(element);
                panels.addElement(panel);
            }
            public function RemoveAllPanels():void{
                //panels.swapElements(swapElementsAt(0,2);
                panels.removeAllElements();
                /*var but:Button;
                but=new Button();
                but.label=name;
                buttons.addElement(but);    */          
            }           
        ]]>
    </fx:Script>

    <mx:ViewStack id="panels" x="0" y="31" width="100%" height="100%" borderColor="#000000"
                  borderStyle="solid" borderVisible="true" clipContent="true" includeInLayout="true">
    </mx:ViewStack> 
    <s:ButtonBar id="buttons1" x="0" y="0" width="100%" dataProvider="{panels}"
                 justificationStyle="pushOutOnly"/>
</s:Group>

这是测试面板，它的大小超过了视图堆栈，它必须裁剪。TestPanel

<?xml version="1.0" encoding="utf-8"?>
<s:Group xmlns:fx="http://ns.adobe.com/mxml/2009"
         xmlns:s="library://ns.adobe.com/flex/spark"
         xmlns:mx="library://ns.adobe.com/flex/mx"
         width="100%" height="100%">
    <fx:Script>
        <![CDATA[
            import spark.components.NavigatorContent;           
            protected function button1_clickHandler(event:MouseEvent):void
            {
                // TODO Auto-generated method stub
                NavigatorContent(this.parent.parent.parent).label="bebe";
            }
        ]]>
    </fx:Script>

    <fx:Declarations>
    </fx:Declarations>
    <s:Button x="163" y="35" width="315" height="209" label="Кнопка"
              click="button1_clickHandler(event)"/>

</s:Group>

当我点击"444“在buuton栏我的内容不裁剪。有什么问题吗？

Answer 1

问题出在下面这行TestPanel自定义组件中：

<s:Button x="163" y="35" width="315" height="209" label="Кнопка"
              click="button1_clickHandler(event)"/>

如果要将任何组件添加到父容器中：-

子组件将考虑相对于父组件的x和y位置。如果想要适配子组件，则应该使用x=0和y=0，以及宽度= 100%和高度= 100%

试试这个，看看输出结果：-

<s:Button x="163" y="35" width="100%" height="100%" label="Кнопка"
              click="button1_clickHandler(event)"/>

再试一次，看看输出结果：

<s:Button x="0" y="0" width="100%" height="100%" label="Кнопка"
              click="button1_clickHandler(event)"/>

您将逐渐了解组件的行为。

希望这能解决你的问题.....
